I have 4 65 gallon grassroots fabric pots that need about 4 2 cubic ft. bags of soil each. I purchased 4 bags of nutrient rich soil at a local nursery and I was going to put one bag of this stuff in each pot and add some organic raised bed soil to fill the rest. Then I was going to add some crab and lobster shell, gypsum, and rock phosphate to the soil. Then I was going to fertile every 1-2 weeks with the tomato and veg fertilizer. Is this too many nutrients? Should I just not add any extra amendments?

Make sure you you read the suggested use and quantities while understanding what each does. You could definitely overdo it.
Yea you gona flame them mf
Tomatoes are very heavy feeders. My experience growing in containers so far shows that even if you start with very rich soil (which yours may or may not be since it doesn’t show percentages of each component) they still benefit fertilization and handle extra fertilization like champs. They even require it after they set a handful of fruits, otherwise production slows down over time.
My advice is once they set a couple of flower clusters worth of fruit to start fertilizing and fertilize every 10-14 days or even once per week depending on how they react.
It likely isn’t too hot to start with. I would probably skip the rock phosphate. I am not sure what the crustacian shells do, but they won’t hurt.
One thing I would reconsider is the raised bed soil. This usually is mostly composted wood waste and can be really heavy and cloddy. If you go this route, you may want to consider adding in some perlite.
Also 65 gallon bags won’t be easily moved, so make sure they are where you want them.
